摘要：
We present the formation of protruding 'blister' microstructures in polyimide and PMMA thin films using tightly-focused femtosecond pulses. We also show that implanting a reflective metal layer in the polymer film lowers the required pulse energies for forming blisters and prevents film rupture.
